Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503132, here are decompositions:

13 + 31503119 = 31503132
29 + 31503103 = 31503132
71 + 31503061 = 31503132
79 + 31503053 = 31503132
139 + 31502993 = 31503132
173 + 31502959 = 31503132
179 + 31502953 = 31503132
191 + 31502941 = 31503132

Showing the first eight; more decompositions exist.
